My 1989 700r4 has been modded with a .500 boost valve, L type accumulator valve assy with pink firm shifting spring, 5600 rpm governor, Corvette servo & piston assy.
I can ratchet shift to any rpm. I have a great snappy 1-2 shift, But My 2-3 has a delay. When I installed the servo, I measure the pin, and it was a little shorter than the spec I have in the manual.
Also automatic shifting at WOT is nowhere near 5600, more like 4600.
